BASIC FUEL TANK VENTING AT A VALUE PRICE
Morrison updraft vent tee with two DN20 (3/4 BSP) female outlets. Basic pressure relief for fuel tanks at a low price point.
What it does
This tee vents fuel tanks during filling and dispensing. As fuel goes in, air comes out through the vent lines. Without proper venting, tank pressure slows your fill rate or creates a safety risk. Two outlets give you flexibility in routing vent lines around obstacles or splitting to separate vent stacks.
Who this suits
Fleet sheds, workshops, and construction sites running basic diesel or petrol storage. If you need low-cost venting that threads into a standard BSP tank fitting and does the job without extras, this is it. Not a high-spec unit and not trying to be.

Frequently Asked Questions
Can't find your answer?
Contact UsWhat is the Morrison updraft vent tee?
It's a basic venting tee that relieves pressure in fuel tanks. Two DN20 (3/4 BSP) female outlets let you route vent lines without additional fittings.
What fuels can I use this with?
Diesel and petrol. Not rated for aggressive chemicals or high-temperature applications.
Do I need both outlets or can I cap one?
You can cap one outlet if your setup only needs a single vent line. Use a BSP plug rated for fuel service.
What does updraft mean?
Updraft vents allow air to flow upward and out of the tank as fuel enters, preventing pressure that can slow fill rates or damage the tank.
What warranty and support do I get?
12-month manufacturer warranty covers defects. For installation questions or bulk orders, contact sales@goind.com.au or 07 3204 2240.
